tolong kerjain 3 soal pleaseee

33) sisi miring belah ketupat = (12/2)^2 + (16/2)^2 = 6^2 + 8^2 = 36 + 64 = 100
akar 100 = 10 cm

cari Tingginya dari rumus Volume
V = la x t
1440 = 1/2 . 12 . 16 . t
1440 = 96t
t = 1440 / 96 = 15 cm

L = 2la + ka . t
2(96) + (4.10) . 15
= 192 + (40 . 15)
192 + 600
= 792 cm (D)

34) V tabung = 22/7 . 7 . 7. 20
= 154 x 20 = 3080 cm^3

V kerucut = 1/3. 22/ 7. 7.7 . 24
= 22 x 7 x 24 /3 = 154 x 8 = 1232

V t + Vk = 3080 + 1232 = 4312 cm^3

35) l.alas = 1/2 . (18+12) . 8
= 15 . 8 = 120 cm^2

miring = 8^2 + 6^2 = 100
akar 100 =10
k.alas = 10 + 18+12 + 8
= 48

Luas = 2la + ka . t
2 (120) + 48 . 9
= 240 + 432
= 672
